I have a vague idea how to solve this problem and I am looking for specific suggestions as I am from mechanical background.

I have a data acquisition system that can take minimum 100mV ac voltage. But my sensor generates a low voltage ac signal with maximum of 30mV peak to peak. So I am looking to amplify the signal before connecting my sensor to the data acquisition system.

In short, I am looking for suggestions or solutions on how to amplify a 0-30mV peak to peak ac signal to a minimum 100mV ac signal without altering the frequency.

Do you mean -15mV to +15mV peak-to-peak or 0 to +30mV peak-to-peak?

What is the bandwidth of the signal? What is the sample-rate of your data-acquisition system?Perhaps you could tell us exactly which sensor this is? And which data-acquisition system.
